A Study for Development and Validation of K Critical Thinking Disposition Test

The purposes of this study are (1) to clearly define the construct of critical thinking disposition which is an affective aspect of critical thinking, (2) to explore component factors of the construct, (3) to develop a measurement instrument for critical thinking disposition, and (4) to test the goodness of the developed measurement instrument. A pretest was conducted to identify component factors of the construct of critical thinking. The results of factor analyses revealed that the 8-factor model shows the best goodness and is consistent with theoretical models of critical thinking disposition. The eight factors are (1) truth-seeking disposition, (2) shrewdness, (3) motivation to implement complex thinking, (4) pursuit of validation and accuracy, (5) openness of thoughts, (6) fairness and independence of thoughts, (7) intellectual curiosity and tenacity, (8) self-regulation of thoughts.
